#
# Shows WHOIS: info including realname and channel names on joins to
# channels.
#
# This script is based on the autorealname script, and shares a little
# code and many ideas with that script. I use the same globals as they do,
# but with totally different fields because their structure was not really
# easy to adapt to a situation where more info is used on one query.
#
# Rewrote all that code, except for parts of request_whois and some init code
#
# I would like to thank Timo 'cras' Sirainen and Bastian Blank for writing
# the autorealname script. It was a good example.
#
# The script contains very simple flood protection in the form that it will
# not allow for more then $max_queued_requests per server at one time to be
# running. It tries to be smart about netsplits, so this should be okay.
# We have a 5-second timeout to make sure we really don't flood, ans also to
# make sure that we don't wait indefinitely for answers that won't come.
#
# Themes:
# You can change the way the WHOIS messages look using the /format command,
# For example:
# /FORMAT ji_whois_success %GWHOIS:%n {channick_hilight $0} \
# is "{hilight $1}"%n on {channel $2}
#
# Will add a green WHOIS: to the line to make it stand out, save your
# formatting in irssi using '/SAVE -formats'
#
# Add 'server: "{hilight $3}"' to the format string to also print the
# server name (Thanks to Svein Skogen for suggesting this)
#
# Add 'flags: "{hilight $4}"' to the format string to also print
# some additional flags for the user. These flags are tailored for
# some unknown irc network but also work quite well on IRCNet and EFNet
# after the 'idle' modifications I added to them. Thanks to
# Francesco Rolando for providing me with the initial patch.
#
# Commands (/JOININFO ...)
# INFO - Show info on and contents of the current cache of this script
# GC - Manually run the garbage collector once
# FORCE - Fake join of a nick to a chan (/JOININFO FORCE ichiban) use with
# care. Useful for testing theme changes, timeouts and the garbage
# collector on a quiet day or network. Will ignore your own nick.
# HELP - Shows help
#
# Settings
# /SET whois_expire_time # time to expire one saves record
# # until this age has been reched no
# # new WHOISs will be put on the server
#
# /SET whois_max_requests # max concurrent requests per server
# # flood protection, keep low
#
# /SET whois_timeout_ms # timeout after which a whois is lost (ms)
# # (default: 5000)
#
# /SET whois_gc_interval_ms # run gc ever x MS (default: 300000)
# # Requires script reload when changed.
#
# /SET whois_debug # 0 = show no debug info, 1 = debug info
#
# /SET whois_printing_level # Level at which all non-debug output is
# # printed, influences logging and IGNORE
# # (default: JOINS)
#
# ChangeLog:
# - Tue Jul 15 2003, pbijdens
# Initial release version 0.5.1
# - Thu Jul 17 2003, pbijdens
# Version 0.5.2
# Added garbage collection for the stored info.
# Added /AWINFO and /AWGC commands to show info and to run the garbage
# collector manually respectively
# Added timeout for the putserv WHOIS making sure we do not record too many
# jobs as BUSY.
# - Thu Jul 17 2003, pbijdens
# Version 0.5.3
# Added settings (whois_...) to the irssi config so there is no need to
# modify the script when changing them
# - Thu Jul 17 2003, pbijdens
# Version 0.5.5
# Making sure the settings are reloaded when they are changed. Added a
# signal handler for that
# - Thu Jul 17 2003, pbijdens
# Version 0.6.0
# Added setting for whois_debug
# Added theme support
# Bugfix for servers sending 401 without 318 no need to wait for
# timeout anymore on those
# Added configurable printing level for the realname+channel messages.
# use /SET whois_printing_level
# Added /AWFORCE command (see above)
# - Mon Jul 28 2003, pbijdens
# Version 0.6.1
# Various updates and bug fixes
# Changed awforce command to strip spaces
# - Wed Aug 13 2003, pbijdens
# Version 0.7.0
# Fixed typo in comment line
# Changed /AW* commands to be /JOININFO <subcommand> and added a
# /JOININFO HELP command. Renamed some subs to make their purpose
# more clear.
# - Wed Feb 2 2004, pbijdens
# Added features for filtering channels from the list, and adding
# support for hilighting channels in colors.
# - Mon Mar 8 2004, pbijdens
# Fixed bug where also on SILCNET the WHOIS queries would be run, now
# this service is restricted to IRC networks. Thanks to Tony den Haan
# for supplying this patch.
# - Mon Mar 8 2004, pbijdens
# Added support for printing the servername also in the output for those
# who want to see it. Thanks to Svein Skogen for suggesting this and
# sending me a patch.
# NOTE: Requires you to add {hilight $3} to your format string manually.
# By default the information is not diplayed.
# - Mon Mar 8 2004, pbijdens
# Added support for additional flags to the WHOIS output. This is stuff
# like IrcOP, Away, Idle and more. Thanks to Francesco Rolando for
# providing the additional patch, which I modified.
# NOTE: Requires you to add {hilight $4} to your format string manually.
# By default the information is not diplayed.
# - Tue Mar 1 2005, pbijdens
# Updated the script for compliance with a wider range of servers,
# and removed some functionality that generally did not work, or break
# on some servers. Been runing on 4 networks now with these patches for
# many months, declaring stable and releasing 1.0.

These settings:
Use /FORMAT to change ji_whois_success, ji_whois_list_header,
